Docs: rework readme

- Fix some typos
- Remove some unnecessary text that was taking space
- Use double quotes in lua examples (this seems to be the convention in
  the source code)
- Sort list of languages so they are easy to find.

 ## Adding parsers

+Treesitter uses a different _parser_ for every language. It can be quite a pain to install, but fortunately `nvim-treesitter`
 provides two command to tackle this issue:
-  - `TSInstall` to install one or more parser. You can use `TSInstall all` to download all parsers.
-  - `TSInstallInfo` to know which parser is installed.
 
-Let's say you need parsers for `lua`, `c`, and `python`, this is how you do with these commands:
+- `TSInstall {language}` to install one or more parsers.
+  `TSInstall <tab>` will give you a list of supported languages, or select `all` to install them all.
+- `TSInstallInfo` to know which parser is installed.
+
+Let's say you need parsers for `lua`, this is how you do with these commands:
 
 ```vim
-:TSInstall c
-Downloading...
-Compiling...
-Treesitter parser for c has been installed
-
 :TSInstall lua
 Downloading...
 Compiling...
 Treesitter parser for lua has been installed
-
-:TSInstall python
-Downloading...

-Treesitter parser for python has been installed

 Cool, lets see which parsers are installed:
